The method of making a decorated film with a metal layer in the form of a given pattern comprises the steps of forming a metal layer on at least one surface of a base sheet through the utilization of the vacuum plating technique and removing a preselected area of said metal layer from said base sheet. When a water-insoluble resin is used, the resin is printed on the metal layer to form a positive resinous pattern and then the printed material is immersed in a metal soluble aqueous solution to remove the exposed metal layer without the resinous pattern. When a water-soluble resin is used, the resin is printed on the base sheet to form a negative resinous pattern and then the metal layer is formed on the surface with the resinous pattern. The resultant material is immersed in water to dissolve the resin and simultaneously remove the metal coated on the resinous pattern together with the resin.

In a method of making a decorated film with a metal layer in the form of a given pattern and comprising the steps of depositing a metal layer on at least one surface of a water-resistant base sheet by vacuum plating technique and removing a preselected area of said metal layer from said base sheet, the improvement comprising: printing a patterned water-insoluble colored coating composition on said surface; printing a patterned water-soluble resin on the resultant printed surface in such a manner that the printed pattern of said water-soluble resin is jig-saw matched with the printed pattern of said water-insoluble colored coating composition; depositing said metal layer on the entire resultant double-printed surface; and immersing the resultant metal-coated material in water to dissolve said water-soluble resin and concurrently remove the metal deposited on said water-soluble resin.
